Hypoxia has been highly proven a hallmark of tumor micro-environment, promoting the malignant phenotypes, playing a crucial role from tumor initiation, progression, invasion, and intravasation to metastatic dissemination and outgrowth. Increasing evidence also showed that hypoxia mediated the abnormal lipid metabolism in cancer by regulating various oncogenic signal pathways. However, it is still unclear but attractive how hypoxia specifically functioned and changed the condition of the tumor micro-environment.

One potential therapeutic strategy for AD is to prevent loss of adult hippocampal neurons. While recent studies have reported that GBE protects against oxidative stress in neurons, the underlying mechanisms remain unclear.

Hypoxia and lipid metabolism-related gene acetyl-CoA synthetase 2 (ACSS2) is involved in tumor progression, but its role in pNENs is not revealed. This study showed that hypoxia can upregulate ACSS2, which plays an important role in the occurrence and development of pNENs through lipid metabolism reprogramming.

Background: Pancreatic neuroendocrine neoplasms (p-NENs) are relatively rare and highly heterogeneous. Dyslipidemia may be related to the risk of developing p-NENs, although dyslipidemia in patients with p-NENs is rarely reported. In this study, the clinical characteristics of p-NENs patients with different lipid levels and their prognostic value in p-NENs patients were evaluated.
View Article and Find Full Text PDFAge-related macular degeneration (AMD) is one of the main causes of visual impairment and severe visual loss, and can progress to two advanced forms-neovascularization and atrophic. The field of anti-AMD drugs has undergone huge developments in recent years, from single-target intravitreal administration to current clinical studies with multi-target and non-invasive agents, offering interesting new pharmacological opportunities for the treatment of this disease. Hence, we summarize some of the approved anti-vascular endothelial growth factor (VEGF) drugs for neovascular AMD, especially their structural characteristics, clinical manifestations, dosing regimens, and safety issues of the anti-VEGF drugs highlighted.

Patients with ECLs were enrolled in the study and underwent endoscopic submucosal tunnel dissection (ESTD) or hemostatic forceps-based ESTD (ESFTD). All patients were divided into three subgroups according to longitudinal length of the lesions (LLLs): >8 cm, 4-8 cm and < 4 cm.

The classical famous prescription Dajianzhong Decoction is recorded in Synopsis of the Golden Chamber written by Zhang Zhongjing in the Eastern Han Dynasty. It has a long history and definite clinical effects, while this prescription has not been manufactured into Chinese patent medicine preparation. We collected many ancient books of traditional Chinese medicine(TCM) by using the method of bibliometrics and got 211 valid data terms which involved 67 ancient books.

The aim of this study was to identify novel biomarkers and reveal potential mechanisms of frailty based on the integrated analysis of metabolome and gut microbiome. In this study, twenty subjects consisted of five middle-aged adults and fifteen older adults, of which fifteen older subjects were divided into three groups: non-frail, pre-frail, and frail, with five subjects in each group.

Although hypoxia has been shown to promote keratinocyte migration and reepithelialization, the underlying molecular mechanisms remain largely unknown. ADAM17, a member of the metalloproteinase superfamily, has been implicated in a variety of cellular behaviors such as proliferation, adhesion, and migration. ADAM17 is known to promote cancer cell migration under hypoxia, and whether or how ADAM17 plays a role in hypoxia-induced keratinocyte migration has not been identified.

Ganjiang Lingzhu Decoction is one of the first 100 classical prescriptions published by China in 2018. According to the published literature, it was found that there is no review on the history, evolution and research progress of this prescription. In order to reflect the history, modifications, quality control and clinical applications, this paper focuses on the origination, evolution, current development and modern studies of Ganjiang Lingzhu Decoction, in the hope of providing a reference for the heritage and innovation of other classical prescriptions.

However, most studies are focused on the effect of bioelectric field on the movement and migration of single epithelial cell; the molecular mechanisms about collective migration of epidermal monolayers remain unclear. Here, we found that EFs dramatically promoted the collective migration of HaCaT cells towards the anode, activated the sheddase activity of ADAM17 and increased the phosphorylation level of EGFR.

Although ARDS is known as an early, common, and life-threatening complication in major burns, the issue of whether or how the EVLW index (EVLWI) correlates with its prognosis has not been identified yet. In this retrospectively study, 121 severely burned adults with ARDS occurred in 2 weeks postburn were analyzed and divided into two groups: survivors (73 patients) and nonsurvivors (48 patients) according to the 28-day outcome after injury.

According to previous study, down-regulation of CD9 contributes to keratinocyte migration, critical for wound re-epithelialization. Nevertheless, it is widely believed that tetraspanin CD9 does not have ligands or function as the cell surface receptor, rather it is thought to associate with other transmembrane molecules, thereby mediate keratinocyte migration.

The extravascular lung water index (EVLWI), which reflects the degree of EVLW in an individual, increases in the fluid reabsorption stage rather than the initial resuscitation stage in severe burn cases. While many factors contribute to EVLWI variation, the risk factors contributing to its abnormal elevation in severe burns remain unclear.
